Specification of Letters'Patent. Patented J 11116 29,- 1915.:

Original application filed A ril 16, 1914,8eria1No. 832,207. Divided andthis application filed January 7,

T all whom it may concern:

Be it known that I, HENRY H. SCHUETTE, a citizen of the United States, and a resident of Napoleon, in the county of Henry and. State of Ohio, have invented a certain new and useful Eccentric; and I do hereby declare the following to be a full, clear,

and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the This invention relates to machine ele-' ments and particularly to an eccentric, and is a division of the application filed by me on April 16, 1914, Serial No. 832,207, for a grain separator. I

The primary object of my invention is to give an eccentric a maximum throw without increasing the outside diameter thereof.

A further object of the invention is to provide simple and improved means for securing the eccentric to its shaft, whereby to enhance the practicability and commercial value thereof.

The invention is fully described in the following specification, and while, in its broader aspect, it is capable of embodiment in numerous forms, a preferred embodiment thereof is illustrated in the accompanying drawings, in which,

Figures 1 and 2 are side and edge elevations respectively of an eccentric embodying my invention. Fig. 3 is a cross-section thereof on the line 00, w in Fig. 2. Fig. 4 is a section on the line y, y in Fig. 3. Fig. 5 is an edge view of the eccentric member, and Fig. 6 is a perspective view of the removable bearing block.

Referring to the drawings, 1 designates a shaft, 2 the eccentric member, which is keyed to the shaft, and 3 the strap member, which rotatably encircles the eccentric member 2 and has the rod 4 projecting therefrom.

The eccentric member is of circular form and has its periphery circumferentially grooved, as at 5, to form a gulde-wa-y for receiving the strap 3. The strap 3 is made in two parts which are, secured together by bolts 6, or in any other suitable manner. The eccentric member 2 is provided at one side ofits axis with a radially-- disposed shaft receiving notch 7 which is of suitable depth to permit the shaft 1, when placed therein, tohave its outer side subs tantially flush with the base of the groove 0, as shown in Figs. 1 and 3a -A key seat 8 is provided in the base of the notch 7 to receive akey 9, whlch also engages in a registering groove or key seat in the shaft 1.

The eccentric member 2 is secured to the of the eccentric member, as shown in Figs.

2' and 4. The block 10 is provided in register with the edge flanges or side walls of the eccentric groove 5 with shoulders 12, and 1s cut away at its outer side between the shoulders 12, 12 to a point in circular register with the base of the groove 5 to permit the eccentric strap 3 to freely turn over the block 10 and assist in holding such block to the shaft. The ends of the block 10 without the shoulders 12 are of segmental form to adapt the looped portions of the clips 11 to engage thereover, as shown in Fig. l. The legs of the clips project inward at the sides of the shaft and through registering openings in respective flanges 14 which are formed on the sides of the eccentric diametrically thereof. Nuts 15 are threaded on the free ends of the clips 11 and coact with the flanges 14 to retain the clips in assembled relation.

It is evident with this form of eccentric and the manner of securing the same to the shaft that it is possible to place the outer edge of the shaft substantially flush or in register with the inner peripheral line of the strap 3, thereby giving a maximum throw to the eccentric without increasing the outside dimensions of the strap. It is also evident that the eccentric can be easily and quickly removed from or secured to a shaft for the purpose of substitution or repair.

I wish it understood that my invention is not limited to any specific construction, arrangement or form of the parts except in so far as such limitations are specified in the claims.

Having thus described my invention, what I claim as new, and desire to secure by Letand member against relative'turning, and an eccentric strap loosely encircllng sald eccentric member and block with its inner periphery substantially flush with the outer sideof the shaft.v V

2. In combination, an eccentric member having a shaftv receiving notch in an-edge thereof, a shaft keyed in the base of said notch, a bearing block closing the outer end of said notch, an eccentric strap, loosely encircling said eccentric member and block with its inner periphery substantially flush with the outerside of the shaft, and meansv for securing the. bearing block tov the eccentric. r

3. In combination, an eccentric. member having a radial shaft receiving notch in an edge thereof, a shaft keyed in the base of said'notch, abearing block seated in the outer end of said notch without the shaft and having its ends projected beyond the sides of said member, clips embracing the extended ends of said block and adjustably attached to said member, and an eccentric rotatably encircling said member and block.

43. In combination, an eccentric member having a radial shaft receiving notch in an edge thereof and having flanges projecting from opposite sides thereof adjacent to the base of said notch, a shaft keyed in the base of said notch, a bearing block seated in the outer end of said notch against the outer side of the shaft and conforming at itsouter side to the peripheral shape of the eccentric member and having its ends projected be- HENRY H. SCHUETTE.
